What Are Superparamagnetic Contrast Media (SPCM)?
Superparamagnetic contrast agents are iron oxide nanoparticles that enhance magnetic resonance imaging (MRI) by affecting local magnetic fields, resulting in signal reduction and improved tissue contrast. Unlike gadolinium-based agents, SPCMs are noted for:
- Lower toxicity profiles
- Better stability within tissues
- Capability for functionalization and targeted imaging
Key Subcategories:
| Subcategory | Description | Examples |
|---|---|---|
| Monocrystalline Iron Oxide Nanoparticles (MION) | Single crystalline form with strong magnetic properties | Ferumoxytol, Ferumoxtran-10 |
| Nanoparticle Clusters | Clusters of iron oxide nanoparticles | Resovist, Supravist |
